Inexpensive rookies require planning. Last year, the Seahawks brought in Percy Harvin, Cliff Avril and Michael Bennett. The 49ers, meanwhile, acquired Anquan Boldin. The Colts made a number of strong middle-class signings, and the Dolphins splurged on Mike Wallace (among others). The common thread? All of those teams are in a window in which they have young quarterbacks on relatively short money. And most have planned to have financial flexibility when the bill comes due on their signal-callers.
